Wimbledon’s Centre Court played host to one of the most captivating upsets of the 2025 tournament on Tuesday, as four-time Grand Slam champion Naomi Osaka delivered a masterclass to defeat world number one Aryna Sabalenka in straight sets, booking her first ever spot in the Wimbledon quarterfinals.
Osaka, who had never advanced past the third round at the All England Club before this year, put on a near-perfect display of power and precision to wrap up a 6-2, 7-6(7-2) victory. The Japanese star dominated every facet of the match: her serve was unbreakable when it mattered, her groundstrokes landed exactly where she intended, and her tactical read on Sabalenka outpaced the top seed’s own aggressive game plan.
The result marks Sabalenka’s earliest Grand Slam exit since the 2022 French Open, and snaps a 122-match streak of avoiding straight-set defeats at major tournaments. It also reverses a three-match winning streak for Sabalenka over Osaka in their previous three encounters across the past three months. This time, however, Osaka was in control from the opening game, matching Sabalenka’s blistering pace step for step and moving around the grass court with unexpected fluidity.
Coming into this tournament, Osaka’s resurgence has been one of the biggest storylines of the 2025 WTA Tour. After returning from maternity leave in July 2023, she spent more than a year struggling to recapture her top form before hiring coach Tomasz Wiktorowski – the former mentor of world number one Iga Swiatek – late in 2024. The coaching change has paid immediate dividends: Osaka reached the semifinals of the 2025 US Open, notched her first ever trip to the second week of the French Open last month, and now has matched that career-best performance at Wimbledon.
When asked about her newfound success on grass, Osaka was quick to credit her team, joking: “The big Polish man! Shout out Tomasz! Shout out to the rest of my team, they are the best. I have so much fun with them and I learn so much from them. I’m so grateful they are on this journey with me.”
“I’ve had so much fun on this run,” Osaka added after the match. “It’s been a long time since I had so much fun on the court. To do it here means a lot.”
The match itself was a showcase of two of the hardest hitters in the women’s game, but Osaka’s controlled aggression set her apart. She broke Sabalenka early in the first set with a blistering winner – one of 21 total winners she hit through the match – and raced to a double break as uncharacteristic errors piled up for Sabalenka. Osaka closed out the first set in just 32 minutes, a stunningly quick start that set the tone for the rest of the contest.
Sabalenka managed to steady herself in the second set, with her powerful serve bailing her out of multiple break points. Heading into a second-set tiebreak, the top seed had plenty of momentum on her side: she had won 21 consecutive tiebreaks at Grand Slams entering the match, and would have been heavily favored to force a deciding third set. But Osaka flipped the script, racing out to a 5-1 lead in the tiebreak and closing out the win on her second match point. After the final point landed in bounds, Osaka pressed her racquet to her forehead, stunned by her own achievement.
For Sabalenka, the result continues a rocky 2025 season by her own exceptionally high standards. After reaching at least the semifinal of all four Grand Slams in 2024, the Belarusian has fallen short of her own expectations this year. While she has tied for the most WTA Tour titles on tour this season, she dropped a second consecutive Australian Open final in a three-set defeat, and collapsed from a set and double break up in the French Open quarterfinals – a result that left her joking she wanted to quit the sport entirely.
Against Osaka, Sabalenka was openly frustrated by her performance, at one point hitting her own head with her racquet in frustration. But the top seed was clear after the match that she was beaten by a better opponent on the day, not undone by her own mistakes. Speaking to reporters just minutes after the final point, Sabalenka struck a measured tone, a contrast to her controversial post-match press conference at the 2025 French Open.
“I didn’t play my best, and she played probably her best. Sometimes that happens,” Sabalenka said. “Sometimes you can go out there and do everything you can and still lose the match. Well done for Naomi. Wishing her the best.”
Osaka will next face Czech 10th seed Karolina Muchova for a spot in the Wimbledon semifinals. Muchova’s upset win over 2024 champion Barbora Krejcikova guarantees that the women’s singles draw will produce a new champion for the 10th consecutive Wimbledon tournament.
